Announcements

Platform | Metrics

Upcoming native support for OpenTelemetry and Prometheus histograms

Starting with Cluster version 1.324, Dynatrace introduces native support for OpenTelemetry and Prometheus histograms, including automatic percentile calculation. This enhancement enables faster detection of performance outliers and simplifies observability workflows.

Breaking change for existing histogram metrics:

In Dynatrace, in your Local-Self-Monitoring environment, you can use the following query in Data Explorer to see which histogram metrics have been ingested:

isfm:active_gate.metrics.ingest.explicit_bucket_histogram.layout.series
:splitBy(metric_key,"dt.tenant.uuid",data_source)
:sort(value(auto,descending))
:limit(100)

This query requires Cluster version 1.314+ to be installed for the metric to be available.

New features and enhancements

Platform | Deployment

Bulk migration of OneAgents between Managed environments

We have simplified the process of migrating multiple OneAgents across environments, enabling centralized control and reducing manual effort.

This feature supports both web UI–based workflows and REST API integration, offering flexibility for manual and automated operations.

For details, see Web UI procedures and API procedures.

Platform | Deployment

Reconfigure IP address of cluster node without full redeployment

Administrators can now update the IP address of individual nodes within a cluster without requiring a full redeployment. This simplifies network reconfiguration and enhances flexibility in dynamic infrastructure environments.

For details, see Reconfigure the IP address of a cluster node.

Platform | Tags

Understand which rule applied a tag to a monitored entity

We have updated the web UI and Monitored entities API to provide information about which specific rule caused a tag being applied to a monitored entity.

In the web UI, you can select a tag to go directly to the source rule in Settings UI for Automatically applied tags or Manually applied tags. See for example this web UI display:

Example of tagging info displayed in web UI

The Monitored entities API v2 includes additional fields source and sourceSetting as part of the tag-information. The source field indicates how the tag was applied, and sourceSetting specifies the associated Settings object. You can use the Settings API to retrieve the object (source rule).

Example Monitored entities API v2 response

{
          "context": "CONTEXTLESS",
          "key": "conditional-load-test",
          "stringRepresentation": "conditional-load-test",
          "source": "Auto tags",
          "sourceSetting": "api/v2/settings/objects/...."
        },

Platform | Data Explorer

Sort dimensions alphanumerically in the metric selector

A new optional parameter is available for dimension sorting in the metric selector. The default is lexical, which is the default value and sorts dimension values in lexicographic order; the other available option is natural, which detects digits in a dimension and sorts according to their numeric value.

For details, see Metrics API - Metric selector: Sort transformation.

Platform | Data Explorer

Fetching metric-key suggestions optimized

We’ve optimized filtering for metric-key suggestions in the Data Explorer, so suggestions now appear much faster when you start typing. This ensures a smooth experience, even when working with large datasets.

Platform | Davis

Problem close time metadata now shown in classic problem details

The classic problem details page now shows the time when a problem was closed in Dynatrace, next to the other lifetime data. This allows you to quickly see the maximum time that was used for alerting profile duration filters when the problem was still in the open state.

Digital Experience | Session Replay

Firefox browser extension added for Session Replay

A Firefox browser extension has been added for Session Replay. A link to the Firefox store will now appear when replaying a session and we identify that the extension is not installed (as was done with Chrome and Edge).

Digital Experience | RUM Web

Control loading and execution of the RUM JavaScript with defer and async

To reduce parse-blocking JavaScript, you can now manage how the RUM monitoring code is loaded and executed by using the async or defer attributes. These attributes can be applied to the following snippet formats:

Platform

Upgrade of third-party Jetty WebServer functionality to version 12

As part of this release, the included Jetty WebServer functionality is upgraded to version 12.0.22 in Dynatrace Server and ActiveGate.

No manual user-invention or downtime is necessary, the upgrade should happen via rolling updates as part of normal version updates.

Note: In certain high-load scenarios, we experienced a slight increase in CPU and memory usage caused by implementation changes in Jetty 12. If ActiveGate instances are very short on resources, we advise a slight increase to avoid potential overload.

OneAgent

Additional code module download options via Deployment API

The multidistro flavor can now be combined with ARM architecture when downloading code modules via the Deployment API.

Extensions

Warning status support

The Extensions 2.0 framework now understands and can produce both WARNING and PENDING status. Those statuses have been added to the already present OK and ERROR.

Breaking changes

Log Monitoring

Log ingest via REST API strictly validates request payload size for compressed payloads

Log ingest via REST API now strictly validates the request payload size for compressed payloads.
